Tuning Kit Top Performances 86cc cylinder/ stroke 44mm Piaggio

Responding to popular demand, Top Perfamces has put together a true tuner kit that is finally available for scooters: the Top Performances 86cc High End Conversion Kit (Cylinder + 44mm Shaft Stroke)

With an excellent reputation on established 50cc bikes/scooters, Top Performances has come up with this 86cc aluminum tuning kit for Piaggio powered scooters (Water Cooled)

The cylinder is made of Nikasil-coated aluminum with a 50mm bore and 44mm stroke, features 6 fuel transfer ports, a bypassed exhaust port and a modular high compression cylinder head.

The exhaust port is very "big" across its width, giving it a unique look. Special attention was also paid to the outer surface of the cylinder with a cooling channel that surrounds the entire exhaust opening for optimal cooling.

The crankshaft included in this Top Performances 86cc Piaggio /Gilera tune-up kit is a reinforced full-circle racing crankshaft with "extended" stroke - 44mm, 85mm connecting rod, bearing, small end bearing 12x15x15mm.

One of the unique features of high-end crankshafts is the use of tungsten weights instead of the standard "caps" for balancing.

In terms of performance, the Top Performances 86cc Tuning Kit Piaggio/Gilera is a Hyper Racing kit and develops 20/22 HP when combined with the appropriate components:
- min. 28mm carburetor
- digital ignition of the inner rotor
- “Hyper Racing” exhaust.

Contains all products pictured

Note: the crankcase must be milled to make room for the 44mm crankshaft and also for the bottom of the cylinder (d=56mm).
